They usually post about new firmware available and the change log on facebook but they didnt post anything about the M8D this time.

Edit: Decided to download it and see if they included the change log within the package, sure enough they did

===M8D V3.07===2025.03.03===
1. Fixed the warning of overcurrent when the current reaches more than 20A when the dual channels are charged at the same time
2. Fix the voltage drift of more than 20A when the output is in dual-channel simultaneous power supply mode.
3. Modify the start voltage of balancing, default -100mV to the always.
